We each have a unique genetic (基因的，遗传的) make-up. Every cell of your body has the same set of about 100,000 separate genes made of DNA. These are the instructions for producing a person. Genes decide everything from the colour of your skin to the way your brain works. You have one of several billion binations of DNA which e from the random(随机的，任意的) mixing of your parents’ genes. Except for identical twins (同卵双胞胎), no one has the same bination as another person. You are unique! You are unique in another way too: in the way you are raised and all the experiences you have from before birth to adult life. These experiences influence you, your behaviour and attitudes, and the choices you make.

But are genes or life experiences more important in shaping your appearance and personality? Scientists are studying twins to find out. One set of twins occurs every 70 births---some are identical and others are non-identical twins. Identical twins are special because they share exactly the same genes and often the same environment. Non-identical twins are more like ordinary brothers and sisters.

Some identical twins have been adopted and brought up in different homes. With identical genes but a different home environment, scientists can study twins to see how much a particular feature depends on the genes we inherit. For example, we know that eye problems, like short-sightedness, are mostly genetic. But resistance to pain is largely dependent on experiences. Genes also influence our eating habits. Identical twins brought up apart often like to eat at the same time of day and feel full after eating the same amount. Non-identical twins in similar circumstances have more varied eating habits. Identical twins are also more likely to follow the same patterns for marriage and divorce than non-identical twins.

Scientists are trying to identify the different genes that influence our behaviour. Some people are thrill-seekers and get into risk-taking and adventurous activities. They take up extreme sports like bungee jumping and possibly take drugs. Scientists have discovered a gene which affects this.

We could ask, “Are our lives determined by our genes or our upbringing?” Scientists are learning more all the time, but it is certainly true that both are important in making us who we are.

A. We cannot easily change our physical appearance.

Avatar has become the most successful movie in 2009. It is about a soldier whose mind is set into the body of a giant blue alien. He was sent to a dangerous planet called Pandora. His mission（使命） is to find a rare mineral（矿物质）. The mineral is the key to solve the earth's energy crisis(危机).

According to the latest figures（数字）, Avatar has become the fastest film ever to make more than 1 billion dollars in ticket sales around the world. When it had been shown in cinemas for several days, it became the most popular film ever made.

James Cameron decided to make Avatar in 1999. However, the means（方法）to realize his vision（影像画面） did not exist yet.
